AUTO-CONVEYER.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application led. September 20, 1919. Serial No. 325,184,

To all whom fait may concern.'

Be it known that i, EARTHEN H. CAM- rinLD, a citizen of the UnitedStates, residing at Florence, in the county of Fremont and State ofColorado, have invented a new and useful Auto-Conveyen of which thefollowing is a specification.

lThis invention relates to an auto conveyer, that is a device adapted tobe used for conveying or pulling automobiles such as pleasure cars,trucks or tractors or motor driven vehicles from mud, sand, ditches orany place where a machine loses the tractive power of or use of one orboth rear wheels, the device being intended to pull the machine at anyangle desired by placing the conveyer in the angle at which the car isto be pulled.

A further object of the invention is to provide a device for thepurposes stated which is provided with means for securing one endthereof to an automobile wheel or the like and for anchoring theopposite end against movement so that upon the wheel being driven, theconveyer will coil around the wheel, thus pulling the machine from whereit may be lodged.

A still further object of the invention is to provide a device of theclass specified which may be made in different lengths or in sections tobe used for short or long pulls or can be employed as a mud or anti-skidchain or tow rope without injury thereto, while also permitting renewalof worn parts and repair at small cost, as well as insuring that theconveyer will not become displaced from the tire of the wheel and whichwill be of simple construction, economical to produce, strong anddurable and which will he prevented from slipping on the ground surface.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed without departing from the spirit of theinvention.

Referring to the drawing Figure 1 is a side elevation showing theimproved. conveyer as in use and connected to the automobile Fig. 2 is aplan view thereof detached from the wheel.

Fig. 3 is an enlarged fragmentary side elevation of a portion of thedevice.

Fig. 4L is an enlarged transverse section taken on the line l-t of Fig.2.

Fig. 5 is an enlarged sectional view of one of the hangers taken on theplane of the section line 5*.5 of F ig. 2, and

Fig. 6 is a transverse sectional view taken on the line 6-6 of Fig. 5.

Referring to the drawings in detail, my improved conveyer is shown asincluding spaced parallel side members 10 preferably of good iiaX ropepicked especially for the purpose, though it is to be understood thatthe essential characteristic of these side members is that they areflexible and strong. These side members are provided at spaced pointsequidistantly along the lengths thereof with pairs of apertures 11located in opposed relation and receiving therein casings 12.

These casings are designed to receive hangers 13 arranged in pairs atopposite ends of webs 14 comprising tread sections extendingtransversely between the side members in spaced relation as specified.These hangers are preferably of metal and riveted or otherwise fastenedto the webs 14; as shown at 15, the hangers being provided withelongated flattened inner end portions for this purpose and having theirouter ends apertured for receiving locking pins 16 transverselytherethrough. These pins are located outwardly of the side members andextend in the same direction as said side members, so that the apertures1.7 receiving them are horizontally positioned.

The webs 1li are preferably made up of heavy canvas and each webconsists of five plies or thicknesses the bottom of which is studdedwith steel lugs as shown at 18 so as to prevent 'the webs or treadsections from slipping. The locking pins 16 are reduced in diameterintermediately of their lengths as shown at 19 and mounted in the endsof the hangers 18 are spring catches 2O which engage the reducedportions and prevent displacement of the pins from the apertures of thehangers.

The side members 10 are of twisted rope so as to give the properstrength and flexibility and have secured thereto near one end of thestraps which are located in so 'i 'tened about a wheel in the mannershown in F ig. l of the drawings, when a vehicle becomes stuck in a bogor the like so as to render one or both of the rear or drive wheelsineffective for traction purposes and `the opposite end isconnected toanY anchor- -ing` member or stake 25 preferably of metal so that it canbe readily driven into the ground.

rllhis connection is effected through the medium of a swivel joint oruniversal link 26, the saine being connected to the side members bybending or tl'irning a piece of rope forming the side members, uponitself or bringing said ends near the staketogether and fastening asspecified. The stake Yis further provided with a handgrip 27 by which itmay be readily withdrawn after use. ln the use of the device, the stakeis driven into the ground yat the forward end oi' the conveyer and thestraps are attached to the wheel at the other end so as to form a memberof a substantially semi-circular cross section or'channel shaped for thewheel whereby te render it impossible Jfor the wheel to slip either way.rfhe drive wheels are-then operated and as the webs or tread sectionsare held from slipping, a direct pull will be provided so that when thewheels start to revolve, the conveyer will coil about the wheel andcause the machine to be conveyed or pulled from the place where it islodged. ln this manner, an effective device for the purpose stated isprovided and onewhich can be readily applied for use and removed afteruse. Y

Having thus described the invention, what is claimed is l. A device ofthe class described comprising spaced side members of rope havingreinforced openings therethrough arranged iu spaced pairs, webs betweensaid sidemeinbers in parallel relation and comprising a plurality ofplies, one of which is studded, hangers at the ends of the webs engagingthe openings, detachable retaining means on the hangers outwardly oi theside members, spaced securing straps Vcarried by the side members nearone end, and a stake swiveled to the other end.

2. The combination with an auto conveyer including spaced side membershaving openings therethrough and webs between Vsaid side members andhaving hangers extending through said openings, said hangers havingopenings therethrough; of pins disposed through said openings and springlatches engaging said pins to retain the same in position. r

In testimony that I claim the foregoing as my own, l have hereto ailixedmy'signature in the presence of two witnesses.
